Subject: Don't activate -funit-at-a-time with -O2 and higher by default, when
X-Git-Tag: v2.0.1~7399
X-Git-Url: https://gitweb.dragonflybsd.org/dragonfly.git/commitdiff_plain/992f6b0eb6cf7bd9f26c45d7c73522c1bcab80ef

Don't activate -funit-at-a-time with -O2 and higher by default, when
propolice is active. There are some bad interactions which can lead
to false negatives under rare circumstances.
